Unlike other companies, being a Senior Engineer isn't just a paygrade or empty title for us here at akeno. It's a distinction! It means you have built successful products in the past, faced mysterious production errors and came out on top of them, know how to get stuff done right, not just fast.
Being a Senior/Staff Backend Engineer means you can see a features implications for the database, API and related services - even for complex topics like scheduling and other NP-hard problems.
You'll be working in our AI & Optimization Team with team mates that "know their stuff". Colleagues who are there when you need them and not afraid to ask when you can help them. We don't have dedicated architects or tech leads because frankly—if you're a true senior—you should be capable of creating a great first draft yourself.
Additionally you will have Full Stack colleagues doing the heavy lifting to implement the algorithms and logics you build into our application.
You will be working at the heart of our application. We are rapidly changing and evolving our core logics and algorithms to achieve ever lasting positive impact on the performance of our customers supply chains. The backend is a hybrid combination of simulation and optimization components.
You will own a part of the simulation engine and be able to influence and take architectural decisions.
What you will be doing:
- Extend our simulation engine (mainly constraint propagation & complex state searches) partially in Rust, partially in Python
- Interface design and evaluation of simulation and optimization components for web services & APIs
- Benchmark performance of critical backend services
- Setup APIs and services to integrate our optimization and simulation backend with the rest of the application
- Development of solvers using different technologies (mostly hybrid systems between heuristics, constraint programming and meta-heuristics)
- Test suite maintenance and extension for simulation and optimization components
